Support device and method for supporting

of a structure

The invention relates to a support device for superstructures and support methods and systems in which such support devices be used.

The invention is particularly, but not exclusively, to devices, methods and systems for temporarily supporting a structure, such as a formwork or a Bracing, directed on piles or other supports, while concrete or the like is poured into the formwork the concrete, which forms a platform or the like, is finally or directly supported by the piles, the formwork being removed after the concrete has sufficiently set, making it self-supporting.

Heretofore, such support devices have included metal hangers that hang from the tops of the piles and which are partially embedded in the concrete after pouring. After removing the formwork, the parts of the hangers, which protruded from the concrete and with the formwork

were engaged, preferably removed, and the remaining (lost) parts of the hangers were concreted over, so that they were completely embedded in the concrete. Such a system has the disadvantage that the lost Hanger parts, even if fully embedded, are prone to corrosion and subsequent damage to the cause adjacent concrete, especially in marine or other adverse environments. j

An object of the invention is therefore to provide said j Avoid disadvantage. !

According to one aspect, the invention consists in a support! device for supporting a structure on a pole or | a similar elongate support, comprising a clamping member which is adapted for releasably attaching and for force-locking \ engaging the support, and wherein the clamping member includes at least one structure-bearing member.

The clamping member may comprise a two-part neck body, the two neck parts being connected to one another by bolts or otherwise are firmly connected, namely after the attachment of the neck parts to the support, the neck body being immovable the support is clamped. The structural element can have one or more flanges or arms which form a part with one or both neck parts. The structure can be immediate be supported on the arms or flanges or it can be supported by an adjustable lifting device or such a ram

is arranged, Figures 4 and 5 corresponding to a plan view and a side view of the lifting and rolling carriage, as shown in Figures 1 to 3, wherein the screw spindle and the Roller is omitted.

According to the drawings, the support device basically includes a clamping member which comprises two neck parts 1, 2 which are made of suitable material, for example they are made of sheet steel and brought into the shape or form shown in FIGS . The two neck parts 1 and 2 generally form a circular opening (Figure 1) for receiving a post 3 and are _{fastened to the post 3 by means of i (} bolts 4 (Figures 2 and 3) to force the clamping member to the post 3 to clamp.

Each neck portion 1 and 2 includes a pair of side arms 5 with horizontally extending flanges 6. The flanges 6 on one or both pairs of arms 5 can directly support a bracing, shuttering or other structure (not shown) or they can support the latter indirectly via one or more support arrangements, one support arrangement generally is denoted by 7. This arrangement comprises an assembled carriage which is slidable along the flanges 6 and Has sides 7b with slots 7a, in which a roller 8 is rotatably mounted. An internally threaded jack nut 9 is mounted on the base 7c of the carriage and an adjustable screw spindle 10 extends through the jack nut and base.

Adjacent to your upper end is the screw spindle 10 with a Provided thicker thread zone 10a, which cooperates with the lifting nut 9. The screw spindle 10 is at its upper end provided with a pressure body or a pressure plate 10b, which or the screw spindle 10 via a ball and socket arrangement 10c is supported, which arrangement is a universal setting allows the inclination of the pressure body 10b relative to the screw spindle. The screw spindle 10 ends at its lower end in a square 1Od, through which the screw spindle with a suitable device (not shown) for turning the screw J

! spindle and the resulting adjustment of the height of the pressure hull 10b can be coupled. ;

The carriage of the support arrangement 7 rests on and bridges the adjacent flanges 6 of the two neck parts 1 and 2, such as It is shown in FIGS. 1 and 3, the screw spindle 10 passing through the slot 11 formed between the adjacent arms 5 outside the bolt 4- hangs down, creating a horizontal Displacement adjustment of the arrangement 7 along the flanges in the direction of the pile 3 and vice versa between the positions is allowed, which are indicated schematically in dashed lines on the left side of Figures 1 and 2, i.e. in a Direction parallel to the axis of rotation of the roller 8. It can be seen from Figure 3 it can be clearly seen that a limited amount of sliding movement the support arrangement is also given in a direction transverse to the roll axis, = according to the game between the screw spindle 10 and the arms 5. However, one serves

Angle arm 12 attached to the carriage and extending from one of the flanges is fastened extending downwards, as a stop around the movement of the support arrangement 7 from left to right in FIG. 3 to limit, and it also serves to prevent the arrangement 7 from accidental separation from the flanges upwards prevent. The dimensions of the support device just described will of course depend on the particular b & w. special Use of the device. In a special embodiment when used with piles in the order of magnitude of 400 mm diameter, where the device supports a load of 16 to 17 tons, the neck parts and the carriage can through Welding from mild steel sheet, which is between 9 »5 and 12.7 mm thick, be assembled, the total weight of the neck parts 1 and 2 and a support assembly 7 between 200 and 260 kg. The total span of neck parts 1 and 2, i.e. the distance between the opposite outer ends the flange 6, as can be seen from Figure 1, can be approximately 1.5 m, and the Stutζanordnung 7 can be about be displaceable or shiftable a distance of approximately 0.31 m on the flanges. The maximum stroke of the screw spindle 10 can be approximately 100 mm.

A variety of support devices as just described can be used in the manufacture of equipment such as marine quays or jetties where large reinforced concrete platforms or the like. By the Obereriden of the piles to be carried, poured in place

will.

Such a system is constructed in such a way that a number of support piles are first driven into the seabed. These Posts, which can be circular in cross-section, each post being able to correspond to pile 3, can be hollow and made of sheet metal be composite, or they can be solid and made of reinforced concrete. Support devices from above are then attached to each post, or at least to some posts, adjacent to the type described upper ends of the piles, decreased by. the elevation of the platform to be poured. This is done by lowering the separated! Neck parts 1 and 2 to the approximate desired position on the j corresponding pile by a crane or other lifting device; direction reached, the neck parts 1 and 2 arranged by means of the bolts 4 on the post and the bolts tightened to firmly attach the neck parts to the post, the arms 5 and the flanges 6 of the support device on each row of piles extending in a direction corresponding in generally across the row.

The support assemblies 7 are then placed on their respective neck bodies arranged by sliding their carriages on and along the flanges 6 from their outer ends. Main carrier or I-beams, which are used to support the formwork between the piles, are then placed, one each across above the stud arrangement 7 of the supporting device of each pile row

after the positions of the support assemblies 7 along the Flanges 6 are set to bring their respective rollers and lifting pressers 10b directly under the beams. Before the Placing the formwork on the beams, or at least prior to pouring the concrete, the beams can initially be placed on the Rollers are at rest, in which case the adjustment screws 10 are turned to raise the pressure bodies 10b, thus the carriers lift off the rollers 8. Alternatively, the pressure bodies 10b can also be raised before the carriers are arranged.

After placing the formwork on the beams (the beam and the formwork are partially and schematically raised in Position 13 and H shown accordingly in Figure 3) the concrete is in the formwork and around the tops of the piles poured, these being embedded in it. After the concrete has set, the screw spindles are turned around the pressure body 10a lower in order to deposit the carrier on the rollers 8. The beams, and if so desired, with the formwork on them, are then rolled outwards on rollers 8 below the poured concrete platform, preferably in one direction from left to right in Figure 3, so that any resulting displacement of the support assembly 7 in the same direction occurs the angle arm 12 is limited and not by the system of the screw spindle 10 on the arm 5 of the neck part 1, whereby the lateral loading of the screw spindle is avoided. The support assemblies are then laterally of the flanges 6 of their associated Neck parts removed, and parts 1 and 2 become loose-

be replaced by other means to the longitudinal dislocation to facilitate the beam relative to the support devices during the assembly and / or removal of the formwork, and the lifting devices can be replaced by other means for at least lowering the girders and preferably also to enable the girders to be lifted, e.g. by hydraulic lifting devices, sand or membrane lifting devices. A support arrangement 7 or their several or equivalents can be on one pair or on both pairs of the opposing flanges 6 of each support device. Alternatively, the support arrangements can also be omitted, in which case the beams rest directly on the flanges 6 or their equivalents.

Although the support devices are primarily intended to be formwork Temporary support, however, the use of the support devices is not limited to this and can therefore can also be used to permanently or temporarily support other structures carried by posts or the like, e.g. passenger walkways (Gangways), walkways, etc.

The support devices can be used in conjunction with non-circular Piles can be used, e.g. piles with an oval, rectangular or polygonal cross-section, in which case the Neck parts 1 and 2 preferably have a cross-section corresponding to these cross-sections in order to have a corresponding pole-receiving To form opening.
